IMPROVEMENT IN APPARATUS FOR COOLING AIR.

Specification forming part of Letters Patent No. 140,375, dated July 1,1873; application filed June 18, 1873.

To all whom it may concern:

Be it known that I, THOMAS D. KINGAN, of the city of Indianapolis,county of Marion, State of Indiana, have invented a new and usefulimprovement upon Patent No. 138,4l1, granted to me on the 29th day ofApril, 1873, for an Apparatus for Cooling Rooms and Buildings, of whichthe following is a specification The nature and object of the inventionwill be fully understood from the following general description a, a,and a, of the accompanying drawings, represent three of theair-refrigerators, for which said patent was granted, arranged inconvenient order. They are to be connected, as shown in the drawing, bythe pipes b and b, through which brine in each can flow into the others.61 is a force-pump of any convenient construction, which draws brinethrough the pipe 0 c, and discharges it through the pipe 6 e. The end cof the pipe 0 c nearly reaches the bottom of the box or refrigerator athe whole device to be arranged substantially as represented in thedrawing.

The said refrigerators a, a, and a, having been placed near the ceilingof the curing-room, and charged with ice and salt, as described in mysaid patent No. 138,411, itwill be found, after a brine has collected inthe bottom of the said refrigerator from the melting of the salt and icewith which it was charged, that it is often desirable, and of greatprofit, to cause a circulation of the brine through the variousrefrigerators to equalize their temperature. To accomplish this theapparatus set forth in this specification has been devised.

As soon as the operator begins to work the pump 61 brine will bewithdrawn from the refrigerator in which 0 is placed, and dischargedinto the refrigerator in which 6 is placed.' This disturbance ofequilibrium will cause a current of brine to flow through therefrigerators a, a, and a, and the tubes 1) and b, from c to c, whichmay be continued until the temperature of all the refrigerators isthoroughly equalized, greatly aiding the efficiency and usefulness ofthe device.

I claim as an improvement upon the said Patent No. 13S,4ll-

The combination of the pump (1, the tubes 0 c and e e, and the tubes 1)and b, with the refrigerators a, a, and a, for the purpose and in theway substantially as set forth.

In testimony that I claim the foregoing specification I have hereuntoset 11] y hand this 13th day of June, 1873.

, THOS. D. KINGAN.
